Abstract: The inter-calibration research between FY-2A IR channel and GMS-5 IRA channel is made by using of the radiance transfer model and matched data analysis. On bases of this inter calibration results, we can merge the two geostationary satellite's IR data together and get a new remote sensing data field with higher temporal and spatial resolution.
